    摘要: A scan of F. tularensis genome for homology to a regulatory protein that controls virulence identified gene FTL0552. A knock out mutation in FTL0552 was created using reverse transcriptase PCR and the construct inserted into F. tularensis. This mutant was defective for survival in macrophages and found avirulent in in vivo testing, where the mutant exhibited reduced levels of pro-inflammatory cytokine production, reduced evidence of histopathology in affected tissues, reduced systemic infection, and rapid clearance of the bacterium. In vivo challenge studies with the FTL0552 mutant using the virulent F. tularensis subsp. tularensis SchuS4 strain show an immune response is induced, and protection afforded, after preexposure to the FTL0552 mutant. Microarray studies revealed 148 genes regulated by FTL0552, including genes located within the FPI that are essential for intracellular survival.

    摘要: A new isolate of Ehrlichia species has been obtained from a patient suffering from ehrlichiosis. The new isolate has been found to be similar, but distinctly different from E. canis. The new isolate is E. chaffeensis and is contained in a cell line of canine macrophage cells on deposit with the American Type Culture Collection under accession number CRL 10679. The new isolate must be contained in a cell line in order to remain viable but may be isolated from the cell line. However, the isolate will not remain viable outside of the cell line. A diagnostic kit and methods for diagnosing ehrlichiosis in humans and for screening drugs toxic to the new isolate have also been desclosed.
